AD737JNZ

Overview

The AD737JNZ is an 8-pin true RMS-to-DC converter IC manufactured by Analog Devices Inc. It operates within a supply voltage range of 10 V to 36 V and supports dual supplies from ±5 V to ±18 V. The device features a wide bandwidth of 2 MHz and a settling time of 4 µs to 0.1%. It provides a maximum output current of 160 µA and maintains a low input bias current of 1 nA. The component functions across an industrial temperature range of -40 °C to +85 °C and is housed in a surface-mount SOIC package.

Feature Summary

• Performs true root-mean-square to direct-current conversion for AC signals
• Supports high-voltage single or dual power supply configurations
• Provides analog DC output proportional to the RMS value of the input signal

Applications

• Power measurement systems
• Audio level metering
• Vibration monitoring

Procurement Notes

Verify the specific suffix 'JNZ' against official Analog Devices documentation to confirm the package type, temperature grade, and lead-free status. Ensure compatibility with required operating voltages and thermal conditions before procurement.

Selection Notes

Select this component when accurate RMS conversion is required for signals with varying waveforms. Consider the 2 MHz bandwidth and 160 µA output drive capability relative to downstream circuit requirements.

Part Context

This part belongs to the AD737 family of precision RMS-to-DC converters. It is designed for applications requiring accurate power calculations and signal analysis where waveform independence is critical.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives such as the AD637 series.
